Abstract
Fracture surfaces of soda lime silica glass failed from controlled surface cracks in diametral compression, under mixed‐mode loading conditions were studied using fractography. Mode mixity was introduced by orienting indent precracks in different directions with respect to the loading axis. The mixed‐mode fracture surfaces were characterized by an absence of the mist region. The hackle markings on the mixed‐mode fracture surfaces appear as lances and differ from those observed on surfaces failed in pure mode I. Atomic force microscopy on the mixed‐mode fracture surfaces revealed that the features at different regions are similar and differ only by scale. Fracture surface measurements for mixed‐mode loading are compared to the measurements for mode I loading. The stress intensity at microbranching was determined to be a constant irrespective of the loading conditions. The practical implications of these observations are that forensic analyses can be used without a priori knowledge of the loading conditions.
